Abstract

L'invention concerne la diversité spatio-temporelle mettant en oeuvre plusieurs antennes émettrices (16, 18) et comprenant un agencement de turbocodage comportant deux codeurs convolutifs, systématiques, récursifs (30, 32), des bits d'entrée étant directement fournis à l'un de ces codeurs, et des bits d'informations étant fournis à l'autre codeur, après entrelacement (34) de groupes de bits d'intervalles de symboles respectifs. Des symboles produits par les codeurs et comprenant des informations systématiques et de parité sont acheminés vers les antennes de manière alternée, dans des intervalles de symboles successifs, afin de créer la diversité spatio-temporelle. L'invention concerne également des agencements conçus pour deux ou quatre antennes, et pour plusieurs codes convolutifs, de même qu'un décodeur itératif.
